Now twist that cage about on your little dick. Come on, bend it every angle that you can think of. Make it hurt, make it cry, make it writhe alongside me in pleasure and pain. Just don't let it escape. You know it belongs in there. You know it needs to be tortured and held oh so tight. It's for its own good, really. You only let it out if it deserves it, and it deserves it so, so much less than it wants to be let out.
Keep going! Make sure it loves this as much as it hates it.
